摘要
以某深基坑工程为研究对象,利用有限元分析软件ABAQUS建立了考虑临近建筑物荷载影响的二维数值模型,模拟开挖实际工况。对土体开挖引起的土体塑形应变及基坑的稳定性进行分析计算,对建筑物位置及基础埋深对基坑稳定性的影响进行探讨。计算结果可为工程设计与施工提供理论依据,也可为类似工程提供参考。
In order to simulate the actual working conditions of excavation in a deep foundation pit project, a two-dimensional numerical model under the load of neighboring structure was built using finite element analysis software ABAQUS with shear strength reduction method, the equivalent plastic strain of soil and the safety factor of the deep foundation pit were analyzed. The influences of neighboring building position and depth base on basal heave stability of excavations are studied. It showed this method may provide a useful reference to the similar engineering.
